Your Questions About Solar Energy Generator Suppliers

Mark asks…

Does the excess solar power you make from your home solar panel go back into the grid?

I know someone that has solar panels on their house. They say that the extra electricity they make goes back into the grid and they get paid for it.

Now i was wondering, as they have no way of storing the electricity(elec) they make, that this means that any elec they make must be used at the time of making the elec, i.e if they happened to be boiling the kettle and the sun was shining then they could immediately use their solar generated elec.

But what if the sum of the elec they generate is greater than what they immediately need?

Then this extra elec goes back onto the grid?

If so how does the grid manage this extra supply of elec(even if it is tiny, it’s still surplus?) as i would imagine the grid already has some way of knowing how much elec should be needed.

Or does this extra supply go back to some storage batteries or however the grid may store elec.

Confusing i know, but basically how does the grid manage the elec they need plus any extra from home users?

If you imagine a river with lots of little streams pouring into it, the more rain the more these streams fill the river adding surplus water, same idea with the elec.

Sending your excess energy to the grid is a very convenient arrangement and small suppliers normally get paid as much (sometimes more!) for the kWh they supply as for that which they draw; often ending up with net income. So you notice no inconvenience or interruption with your power supply due for example to the vagaries of batteries.

No one seems to address your central question about where the supplied energy goes. Well, it may, as you say, ever so slightly upset the balance of input and output power on the grid and this will cause all the generators and the grid frequency to speed up just a tiny amount. Because of such imbalances between supply and consumption occurring from minute to minute on the grid, the frequency is constantly monitored and generator loads are always being adjusted to maintain the frequency which can nevertheless vary by 1 or 2 percent from its nominal value at any time. Over a whole day the frequency is adjusted so as to achieve exactly the correct total number of cycles, which keeps any mains-powered clocks at the correct time. So an extra 2 kW that you supply may be taken by a load which happens to switch in at the same time and if not then ultimately the load being supplied by a generator somewhere will be reduced by 2 kW. In the end then, there is an energy storage buffer in the grid in the form of the kinetic energy of its connected generators but it is not much and requires pretty continuous control to stabilize it.

James asks…

Anyone know where I could access solar panel and wind generator for small home from reliable supplier? Thanks?

Try to help small village home with their drought, electricity, farming, small industry, pump and water problems. They got plenty of wind and sunshine but rather dispense with fuel operational cost. Perhaps wind generator and solar panel generator could be the solutions. Besides being a good standby reliable no cost operation it also help prevent greehouse emission. Looking for a reliable products and supplier both for sosial and commercial purpose. Appreciate any website you could introduce me to. Thank you.

i know that tractor supply company carries solar panels but they are not high producing. Each set cost around 300 bucks not including the batteries. I’m going to use complete solar energy for my house. I figured that it would take 3 sets of solar panels from tsc. Each set using 4 marine batteries would cost 2500 to 3000 bucks and it would produce enough power run my most basic energy needs. As far as wind mills i haven’t checked that idea out yet but i will soon enough. I hope that you find what you need. Good luck.
